We are so impressed with our 450h. The handling is excellent; it glides and flies down the road. The steering is tight and the car responds with little effort. We took a trip with our two adult children and a 14 year old; the middle seat is a bit tight, but it handles full capacity comfortably for the most part. Tech features are fun and mainly intuitive. The mouse is fun and useful. Voice navigation has limits but reads well. We love the heated/cooled front seats and classy interior; love the interior lights. Don't like the park assist; it over reacts and is annoying; other downside is it tends to be a little underpowered at times, but nothing major. Overall a total winner!
Handling is extremely responsive; gauges are well designed and attractive, easy to read both day and night; navigation is excellent, visibility is great, love the interior lights for reading and makeup. The keyless entry is great, love the heated and cooled seats and seat adjust features are great.
Have pass assist instead of park assist; sonar would be much better used for this. Navigation needs to be more intuitive. Expand role of mouse; it's such a great feature, and could be used for other functions.
